Fig. 5

Interpretation of the equivalence using 9 atlases in multi-atlas brachial plexus autosegmentation compared with using more (10–11) and fewer (8-7-6-5-4) atlases with Patch label fusion. Using 10 atlases is equivalent to using 9 atlases (yellow marked). The shaded area covers the equivalence range of 10 %. □ = observed point estimate of the outcome difference in each number of atlases, corresponding error bar = two-sided 90 % confidence interval (caps at each end = lower and upper bar bounds of confidence interval). DSC, Dice similarity coefficient; CI, confidence interval
